Community Claude Code skills live in three places: SkillsMP (the largest dedicated marketplace), GitHub repositories tagged claude-code-skills, and curated directories like the awesome-claude-skills collection. Each has different quality signals and different installation friction. Claude Code's active user base grew 300% between May and July 2025 (Anthropic via The New Stack, July 2025), and the community skill catalog expanded with it. At Agent Engineer Master (AEM), we build production-ready Claude Code skills for clients and review community submissions regularly. The patterns below reflect what we actually see in the wild.

TL;DR: The fastest path to useful community skills is SkillsMP for volume and GitHub for depth. SkillsMP hosts over 700,000 skills (Anthropic partner platform, 2025). Most are prompts in a trenchcoat. A few are genuinely built. Knowing the difference takes 90 seconds if you know what to check.

What Platforms Host Community Claude Code Skills?

SkillsMP is the largest dedicated marketplace, with over 700,000 skills indexed across 800+ job role categories (SkillsMP, 2025). GitHub hosts better-engineered skills through tagged repositories and curated lists like awesome-claude-skills. SkillHub and Agent37 are smaller platforms with stricter submission review, suited for production use.

SkillsMP is the largest. It hosts over 700,000 skills as of 2025, searchable by category, tag, and download count. The interface lets you preview the SKILL.md file before downloading. Volume is high. Quality variance is extreme, from precisely engineered production tools to single-paragraph files with no output contract and no description field that would actually trigger.

GitHub hosts the skills that are better-built. Search for repositories tagged claude-code-skills or browse the awesome-claude-skills curated list maintained by the community. The VoltAgent/awesome-agent-skills repository alone curates 1,000+ skills from official development teams including Anthropic, Vercel, Stripe, and Cloudflare (VoltAgent, 2025). As of April 2026, there are 773 public repositories tagged claude-code-skills on GitHub, ranging from single-skill repos to libraries of 200+ (GitHub Topics, April 2026). GitHub-hosted skills come with version history, issue trackers, and contributor discussion. A skill that's been around 6 months with active issues and pull requests has been stress-tested in ways a brand-new SkillsMP upload hasn't.

SkillHub and Agent37 are smaller platforms with stricter submission review. Fewer skills, but the bar check is tighter. These are worth checking when you need something for production use rather than experimentation.

"Developers don't adopt AI tools because they're impressive, they adopt them because they reduce friction on tasks they repeat every day." — Marc Bara, AI product consultant (2024)

The practical implication: the best community skills are the ones that already exist for your specific repeated task. With 85% of developers now using AI tools regularly (JetBrains State of Developer Ecosystem 2025, n=24,534), the community skill ecosystem has grown to match real workflow needs. Search by workflow name, not by topic.

How Do I Search SkillsMP Effectively?

Search by specific task name, not by topic or tool category. Skills are indexed by their name and description fields, so a search for "TypeScript code review with output contract" finds better results than "code review skill." Filter by 500+ downloads for minimum quality signal and by recency to avoid skills written for older Claude behaviors.

Don't search "code review skill." Search "TypeScript code review with output contract." The reason: the skill name field and description field are what get indexed. Skills named generically rank above skills named specifically. Better skills use names like reviewing-typescript-prs or drafting-github-release-notes, not helper or code-tools.

Filter by:

  • Category: Match the task domain first (writing, engineering, devops)
  • Downloads: 500+ downloads is a reasonable quality threshold. Not because popularity equals quality, but because high-download skills have been installed by people who notice when they break
  • Last updated: Community skills decay. A skill last updated 18 months ago references Claude behaviors that have changed

After finding a candidate, preview the SKILL.md before downloading. The quality signals are fast to check.

What Quality Signals Should I Check Before Installing?

Check four signals: a single-line description under 1,024 characters with an imperative trigger pattern, an output contract naming what the skill produces and what it does not, reference files for domain knowledge, and an evals.json confirming the skill was tested before release. These four checks take 90 seconds and catch most fair-weather skills before you install them.

  1. Check 1: The description field. Open the SKILL.md and read the description frontmatter line. It should be a single line (not multi-line), under 1,024 characters, and written with an imperative trigger pattern: "Use this skill when..." or "Invoke when the user asks to...". A multi-line description means the skill will not trigger automatically in production.
  2. Check 2: The output contract. Does the skill define what it produces AND what it does NOT produce? A well-built skill says: "Produces: a 3-section code review with severity ratings. Does not produce: implementation fixes or rewritten code." A skill without a "does not produce" clause scope-creeps on every run.
  3. Check 3: Reference files. Does the skill include reference files for domain knowledge? Skills with no reference files pack everything into SKILL.md. That works for simple tasks. For anything with more than 5 steps or significant domain context, it suggests the engineer skipped progressive disclosure architecture.
  4. Check 4: Evals. A skill with an evals.json was tested before release. A skill without one was probably run twice and declared working. Fine for experimentation, not for production.

The description field is the highest-leverage check. A study of 650 automated activation trials found that a directive-style description ("Invoke when the user asks to...") is 20x more likely to trigger the skill automatically than a passive description (Ivan Seleznov, Medium, February 2026). A separate audit of 23 community skill files found that 61% had structural issues that silently degraded how Claude interpreted them (thestack_ai, dev.to, March 2026).

In our bar checks on community skills submitted for integration into client projects, 60-70% fail on the description field alone. They work via slash command. They never auto-trigger.

How Do I Install a Community Skill I've Downloaded?

Place the skill folder inside .claude/skills/ for project-level or ~/.claude/skills/ for user-level, verify the path resolves to {skill-name}/SKILL.md, then test auto-triggering in a fresh session with no prior context. All three steps are required: skipping the fresh-session test is how undiscovered description-field failures make it into production.

  1. Step 1: Place the folder. Community skills ship as folders with a SKILL.md at the root. Place the entire folder inside .claude/skills/ in your project (project-level) or inside ~/.claude/skills/ (user-level). The folder name becomes the skill's identifier. Keep it lowercase and hyphenated.
  2. Step 2: Verify the path. The skill must live at .claude/skills/{skill-name}/SKILL.md. One level too deep and Claude won't find it. Run /skills in a new Claude Code session to confirm the skill appears in the list.
  3. Step 3: Test in a fresh session. Start a new session with no prior context. Describe the task the skill handles in natural language, without using the slash command. If the skill auto-triggers, the description field works. If it doesn't, invoke it manually with /skill-name and check whether the description needs adjustment.

If the skill comes from GitHub, clone the repository and copy the specific skill folder out. Alternatively, add the repository as a git submodule inside .claude/skills/. The submodule approach makes updates simple: git submodule update --remote pulls the latest version without manual file copying.

What's the Difference Between Project-Level and User-Level Installation?

Project-level means the skill is available in one specific project, committed to version control and visible to every team member who clones the repo. User-level means it's available in every Claude Code session on your machine, but invisible to collaborators and outside version control entirely.

  • Project level: .claude/skills/{skill-name}/ committed to the repo, shared with the team
  • User level: ~/.claude/skills/{skill-name}/ on your machine only, not visible to collaborators

The default for community skills is project-level. This keeps them under version control and makes their presence explicit. User-level installation is right for general-purpose skills you use across all projects: a writing style enforcer or a meeting notes formatter.

Be careful with user-level installation of untested community skills. A skill with an aggressive description field triggers across all your projects, not just the one you were testing it in. That gets disorienting fast.

FAQ

Community Claude Code skills are safe at the file level: a SKILL.md is a markdown text file with no execution capability. The practical risks are behavioral. Skills can trigger when they should not, produce output in the wrong format, or fail on edge cases the author never tested. The questions below address the most common concerns before and after installation.

Are community Claude Code skills safe to install?

A SKILL.md file is a markdown text file. It cannot execute code on its own. The risk is behavioral, not technical: a badly written skill triggers when it shouldn't, produces output in the wrong format, or misses edge cases. An empirical study of 42,447 skills found that 26.1% contained at least one vulnerability pattern, including prompt injection and data exfiltration instructions (arXiv 2601.10338, 2026). Review the SKILL.md before installing. Never install a skill containing Bash tool instructions you don't understand.

Can I use community Claude Code skills for free?

Most community skills on SkillsMP and GitHub are free. Some creators charge for premium skills, particularly for complex production-grade builds. Paid skills remain a small share of the market as of 2025, with most monetization happening through consulting and custom commissions rather than per-skill pricing.

How do I know if a community skill works with my Claude Code version?

Check the skill's README for any version notes. Skills referencing Claude Code features introduced after a specific version do not work on older installs without modification. After installation, run /skills in a new session and look for errors in the startup output.

What's the awesome-claude-skills repository?

A community-maintained list of high-quality Claude Code skills hosted on GitHub. It's curated by contributors who review submissions before adding them. It's not a platform with download mechanics: it's a list of links to repositories. Each skill in the list has been reviewed by at least one contributor other than the author.

Can I install multiple skills from the same GitHub repository?

Yes. Many repositories ship as skill libraries with multiple skill folders inside. Copy each folder individually into .claude/skills/. You don't need to install everything in a repository.

Do community skills update automatically?

No. Skills are static files. Once installed, they stay at the version you copied. If you installed via git submodule, run git submodule update --remote to pull updates. Otherwise, check the source repository for updates and re-copy the folder when a new version ships.
